Hey Bob, my mate's got a set of Variobars for sale -they're actually for a later model Tuorno and I think they're 51mm - I know they were a couple of mill too small for my 53mm Showas ().
I seem to remember that the old model R Ohlins are 51mm too - anyone able to confirm that? Maybe you can measure your forks.
He wants £125 for them and they've never been fitted so are as new (his dog ate the box though). That is around half the new price.
PM me if you're interested and I'll let you have his mobile number.

Also I will need to check the size, is it 51mm across the top of the fork?
Bob

The best bet is to measure your fork diameter just underneath the top yoke with a set of calipers if you can. Then if you phone Gareth (my mate) he can do the same with the bars, just to make sure. They are really nice bits of kit and give you a 40mm rise plus I think you can angle them up a bit to give you a little more rise (not quite sure about this, you'll have to ask him).
I'd have had them myself if they fitted mine.
